Sony KP43HT20 stuck in standby with 6 flashes

Hey guys!

 A couple days ago the TV started whining for a few seconds after startup, then Saturday morning I woke up to the dreaded "Daddy, the tv won't turn on!" So anyway, when you hit the power button it clicks 4 times (sounds like a relay firing) and then goes to standby flashing code 6. the tubes never seem to light and the sound never comes on. My DMM is at work so I can't start on it until tomorrow. The manual says its a shorted or overloaded +5V, any ideas where to start?

 Thanks in advance,

-John

Update:

Update:
OK, so with the B and AD boards removed it's the same error. I read the +5 on CN12 pin 17 at 4.91 during startup. Is any of this making since? I'm not sure where to go next.

ps. Larry, are you out there?
